Horizontal Machining 4‑Axis


Horizontal Machining 4-Axis

The a61nx is a 500mm, 40-taper production horizontal machining center. The a51nx and a61nx share key machine technologies that take part productivity, accuracy and machine reliability to the next level.  Robust casting design and large roller-type linear guides ensure that the entire a61nx work envelope can be effectively utilized.

The 14,000-rpm high-speed, high-power spindle features 303 Nm of torque.  The machines stiffness and rigidity supports thorough utilization of the spindle power and torque to tackle ferrous applications that traditionally would be run on 50 taper machines.

Technical Specifications

a61nx Horizontal Machining Center

Multiple technologies on the a61nx reduce non-cut time, providing benefits in automotive and high volume part production.  Inertia Active Control monitors motor load and estimates total fixture weight.  With this information IAC optimizes the acceleration and deceleration of the heavily utilized B and Z-axis.  The spindle takes full advantage of the duty rated torque to optimize start / stop responsiveness, leading to 20% reduction in tapping time compared to the previous model. A standard Vision type Broken Tool Sensor resides in the ATC magazine where it automatically confirms the condition of drills, taps and other single point tools.

The a61nx production machining center is available in a tall column (730mm) version for part applications that require larger strokes. Unique way-cover design, dual-supported tool-change arm and Makino spindle technology provide the foundation for industry-leading reliability.
